I was able to get the third model on my list above to work. At a promotional discount of 40% from the list price of $69, it was a much lower cost and functional alternative than the 3.0 CarlinKit Ai Box.
As for the dongle itself, the initial setup was quick, the LCD scaling is proper and identical to native Car Play, the connection is stable, and there is very little to no latency after the unit initially connects. Connection persistence is good, it auto connects every time the car power is turned on. Phone, Musicolet (music player), Google Maps apps, and othe AA apps all work as expected. The only issue that I see is that Night mode in Google Maps does not persist albeit I have set it up to Night mode on my phone's AA app, but the dark mode in other apps persist. I don't really use Google Maps and prefer the native navigation of the car as it makes full use of cockpit LCD panel real state instead of running in a sub rectangle similar to native Apple Car Play. Other restrictions previously reported are there, i.e., you cannot use the pilot LCD to extend either AA or Car Play. However, I am able to run apps other than Google Maps for example Musicolet on AA, then switch to native navigation as well as other native apps and they all function as expected. The dongle comes with built-in Netflix and Youtube and both apps function for as long as you connect the dongle to a network hotspot.
Keeping my fingers crossed when Lucid releases AA, it takes full advantage of LCD cockpit panel but that remains to be seen.
